Answer: f(x) has the largest slope
Step-by-step explanation: g(x) has a slope of 1/2 since in the equation y=mx+b, m is always the slope.
h(x) has a straight slope of 1 since he gains one level each time he plays
And finally f(x) has a slope of 3/2 because every time x increases by 2, y increases by 3
